The paper deals with the problem of assessing the characteristics of electromagnetic wave scattering on electrodynamic objects with a complex shape. A combined approach, which is based on the use of statistical methods, methods of fuzzy estimation, and expert analysis, is proposed. A numerical estimate was determined for the index characterizing the level of scattered electromagnetic fields. Linguistic values of the indicators based on expert evaluations were compared. Numerical evaluations of the characteristics of the electrodynamic objects surveyed were given. Based on the formed information base, the frequency of occurrence of different responses was calculated for the analyzed groups, which included objects with over reflections (which was considered as the main group, and objects without over reflections (which was considered as the control group). The values of the electromagnetic wave scattering angle limits under the analyzed scattering conditions were demonstrated.

This article presents the research results of JDE algorithm for detection and tracking athletes in video data. The developed convolutional neural network was trained and tested on the NVIDIA DGX-1 supercomputer. To analyze the quality of the model, MOTA metric was used, which is related to how the human eyes track targets in the video stream. The detection and tracking people on video data is relevant to many tasks of computer vision, in particular, in sport to collect statistics about players. The quality of JDE algorithm was assessed by the video fragments of basketball games filmed in the sports halls at P.G. Demidov Yaroslavl State University.

This article is devoted to the issues related to engineering implementation of methods for building-up the linearity of transmitters and mathematical methods for correcting the parametric non-linear distortions of power amplifiers. Methods for constructing broadband power amplifiers for short-wave transmitters with various types of modulation during information transmission. Possible ways of implementing the various methods of automatic system for monitoring the parameters of a power amplifier in accordance to a specified level of linearity and amplitude response. The problem of obtaining high linearity of a power amplifier and the possibility of its solution by various methods or their combination is determined. Methods of preemphasis of the signal fed to the input of a power amplifier and the precorrection of the modulus of transmission coefficient of a power amplifier are investigated. It is shown that the use of these methods makes it possible to obtain a high path linearity and high efficiency, however they are difficult to implement, and therefore are not currently suitable for use in portable equipment. The greatest attention is paid to the method of using reverse feedback between the signal envelopes at the power amplifier input and output. This method of building-up the linearity of a power amplifier turns out to be preferable for paths of small transmitters.

Wi-Fi is a technology widely spread around the world. The appropriate infrastructure allows users of public Wi-Fi networks to maintain a stable level of Internet communications and at the same time remain mobile. However, Wi-Fi connection is vulnerable to several computer threats that can compromise confidentiality, integrity, and availability of information transmitted by Wi-Fi clients. Among the most notorious Wi-Fi attacks is the rogue AP attack, a common way to detect which is to scan the air and analyze intercepted packets with AP information. Since the Wi-Fi frequency band is divided into channels, the scanning device must switch between them in order to capture packets in all frequency bands. The paper presents the results of an experimental study that establishes the dependence of Wi-Fi access points detection during scanning with sequential and random channel hopping. The research results were used to optimize the Wi-Fi attack detection system.

Despite the fact that electronics over the past decades has been developing with great intensity. Modern industry needs to master new high-tech solutions to create efficient power-supply systems and energy storage devices for high reliability equipment. Various fields of science and technology are increasingly faced with tasks that require the use of accurate and stable devices. In this regard, there is a problem of assessing the quality and performance of electronic components in real operating conditions. The main purpose of this article is to assess the feasibility of incoming quality control of chemical current sources using the example of supercapacitors.

One of the important domains of digital signal processing is the development of IIR allpass digital filters that differ in phase response, and the magnitude response of which is constant at all frequencies. This paper is devoted to the extension of the new approach developed by the authors to the synthesis of IIR digital filters with a finite word length to allpass filters. This approach is based on the fact that the finite wordlength is taken into account even before structural synthesis at the stage of calculating zeros and poles. The calculated values of zeros and poles are final. The next stage of structural synthesis does not distort these values. At the stage of structural synthesis, structures are generated. In this paper, the topography of the poles and zeros of an allpass IIR digital filter with a finite word length is studied. These results are intended to be used at the first stage of the approach developed by the authors.

The paper presents a study of the possibility of decomposition of a damped sinusoid in a turn of a meander microstrip line. To do this, firstly, the properties of a damped sinusoid, which can be used to reduce the amplitude of the output signal, is analyzed. Then, simple theoretical foundations of the approach are proposed. The simulation demonstrated that the input signal can be attenuated for three signal frequencies f0=1,3, and 10 GHz. Several options are considered that minimize the amplitude of the output signal. First, we show the possibility of complete signal decomposition, as a result of which the amplitude was attenuated up to 3 times. Then, we consider the possibility of partial decomposition. In this case, the amplitude is decreased by superposition and mutual compensation of half-waves of a sine wave of different polarity. As a result, a decrease was of up to 3.05 times. finally, we present the possibility of reducing the length of the turn to 3.4 times while maintaining attenuation efficiency. The results obtained indicate that these approaches are promising and there is a need to search for the possibility of their practical implementation.
